  • Straightforward Installation: Threaded connections on both ends allow quick, tool-based installation behind the wall or at an accessible supply point.

Eastman 20366 – Frequently Asked Questions

1) What does the Eastman 20366 adapter actually connect, FIP to hose thread?
The Eastman 20366 takes a 3/4 inch female iron pipe (FIP) thread on one end and a 3/4 inch female hose thread on the other. So it threads onto male 3/4 inch iron pipe or a male-threaded fitting, and gives you a female hose connection for a garden hose, washing machine hose, or any hose-end device. Both ends are female, which is the part people get wrong when ordering.
2) Can I use the Eastman 20366 to hook a washing machine hose to a 3/4 inch threaded stub-out?
That is one of its intended uses. With a 3/4 inch FIP end it threads onto the male 3/4 inch pipe stub, and the 3/4 inch female hose thread end accepts a standard washing machine supply hose directly, no second adapter needed. The washing machine hose has to be a male hose thread end, which is the standard.
3) Is 3/4 inch female hose thread the same as 3/4 inch FIP? Do I need an adapter like the Eastman 20366?
They are not the same, and that is exactly why this fitting exists. 3/4 inch garden hose thread (GHT) and 3/4 inch iron pipe thread are different thread forms and pitches, so a hose will not thread into a 3/4 inch FIP pipe fitting even though the nominal size matches. The 20366 bridges the two in a single piece.
4) Will the Eastman 20366 work for a hose bibb or sillcock rough-in?
Yes. It is sized at 3/4 inch, which matches common residential and light commercial hose bibb connections, and it is called out for hose bibb and sillcock installations as well as utility sink and outdoor faucet rough-in. You thread the FIP end onto the supply piping and the female hose end takes the hose-end device.
5) Do I need a washer or tape with the Eastman 20366?
The 20366 is a threaded fitting on both ends and installs with a wrench. The FIP side is a tapered pipe thread, so it seals with thread sealant or PTFE tape. The female hose side seals against the hose's rubber washer, the same as any garden hose connection, so nothing goes on those threads.
